Groups of four Atlantic salmon parr were established and the dominant individual identified. Feeding responses were then observed in the remaining (subordinate) fish housed in one of three conditions: in the same compartment as the dominant fish (ful

Natural selection has tailored the developmental characteristics of animals to the natural ranges of variation of their environments, so that human restriction of those environments tends to restrict the range of variety within species dependent on t

Maturation is the allocation of energy to growth and differentiation of germinal tissue to the ultimate production of gametes. In Atlantic salmon Salmo salar, maturation begins in the egg soon after fertilisation and continues intermittently until th

Tagged 2-year-old trout smolts, Salmo trutta , were stocked into River Isojoki in 1996, 1997 and 1998 (a sea trout strain), and Lake Konnevesi in 1997 and 1998 (a brown trout strain) in April, May or June–July. Stocking dates were determined in res

In an experimental flume tank, two-year-old, 20 cm Salmo trutta from both anadromous and freshwater resident stocks showed increased downstream movement, mostly diurnally, as the water temperature rose, from early May to early June, most intensely fr

Salmonid life histories are characterised by the ages at which the two primary developmental conversions, smolting and sexual maturation, are made. For Atlantic salmon, the critical seasons at which the physiological decisions are taken are thought t

Summary The great diversity of life-history patterns in the salmonids has stimulated many theoretical studies. However, virtually all studies are based on ultimate considerations, in which predictions are made by comparing the expected reproductive s

During a period of temperature increase from 8.8 to 11.2 °C from May to August, maturing one-sea-winter Atlantic salmon showed decreasing appetite from early June, to little or no food intake by early July. In contrast, non-maturing siblings increas
